## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application is based on and claims priority under 35 U.S.C. §119 to Korean Patent Application No. 10-2016-0016511, filed in the Korean Intellectual Property Office on Feb. 12, 2016, the disclosure of which is incorporated by reference herein in its entirety.
TECHNICAL FIELD
The present disclosure relates generally to an electronic device and method of wirelessly transmitting and receiving signals therefor.
BACKGROUND
Electronic devices such as smartphones and tablet personal computers are extensively used because they are easy to use and easy to carry. Such an electronic device has a socket (e.g. earphone jack) to which an accessory can be connected.
The electronic device may use an accessory connected to the socket as an antenna. For example, when the earphone plug of an earphone is inserted into the earphone jack of the electronic device, the ground terminal of the earphone may be connected to the communication circuit of the electronic device. At this time, the ground line of the earphone may serve as an antenna. The electronic device may receive a Digital Multimedia Broadcasting (DMB) signal and/or an FM radio signal through the ground line of the earphone.
Meanwhile, the electronic device may include a codec circuit to send and receive an audio signal to and from the earphone. To increase the performance of the earphone (e.g. sound quality), the ground of the earphone may be connected to the ground of the codec circuit in the electronic device.
The electronic device may have a socket (e.g. earphone jack) to which an earphone (e.g. 3 or 4 pole earphone) can be connected or inserted. The electronic device may use the ground terminal of the socket for receiving a radio signal or for extending the ground of the earphone. As the ground terminal of the socket is connected with the ground of the communication circuit and codec circuit, a line may be used in common in the electronic device.
However, the width of the commonly used line should become large to enhance audio performance of the earphone (e.g. low crosstalk); and the width of the commonly used line should become small to enhance radio performance (e.g. impedance matching). Hence, it may be difficult for the electronic device to achieve audio performance and radio performance at the same time. In addition, when the commonly used line becomes long and the socket is placed at the lower end of the electronic device, it may fail to mount a specific component (e.g. inductor), which is to be located at the start point where the path leading to the communication circuit and the path leading to the codec circuit are separated, close to the socket owing to the lack of mounting space. In this case, the electronic device may fail to achieve audio performance and radio performance at the same time.
SUMMARY
Various example aspects of the present disclosure address at least the above mentioned problems and/or disadvantages and provide at least the advantages described below. Accordingly, an example aspect of the present disclosure is to provide an electronic device that can enhance both audio performance and radio performance by replacing the commonly used line with separate lines, and a method of wireless signal transmission and reception therefor.
In accordance with an example aspect of the present disclosure, an electronic device is provided. The electronic device may include: a housing having an opening; a connector socket disposed in proximity to the opening and configured to receive an external connector having a plurality of contact terminals through the opening; a ground connected to the connector socket; a codec circuit disposed in the housing and electrically connected with the connector socket; and a communication circuit configured to process a radio signal received from the outside of the electronic device. The connector socket may include a first contact terminal and a second contact terminal that configured to electrically contact one of multiple contact terminals of the external connector when the external connector is inserted into the connector socket. The ground may be electrically connected with the first contact terminal. The codec circuit may include a first port that is electrically connected to the first contact terminal through a first electrical path. The communication circuit may be electrically coupled with the second contact terminal through a second electrical path different from the first electrical path.
In accordance with another example aspect of the present disclosure, a method for transmitting and receiving radio signals in an electronic device is provided. The method may include: detecting whether an external connector having multiple contact terminals is connected with a connector socket having a first contact terminal and a second contact terminal that are configured to electrically contact one of the contact terminals of the external connector; and electrically connecting, when the external connector is connected with the connector socket, the first contact terminal to a first port of a codec circuit electrically connected with the connector socket through a first electrical path, electrically connecting the second contact terminal to a communication circuit through a second electrical path different from the first electrical path, and causing the communication circuit to receive a radio signal through the second electrical path.
In accordance with another example aspect of the present disclosure, a computer-readable storage medium storing program instructions is provided. The program instructions, when executed, cause one or more processors of an electronic device to detect whether an external connector having multiple contact terminals is connected with a connector socket having a first contact terminal and a second contact terminal that are configured to electrically contact one of the contact terminals of the external connector, to electrically connect, when the external connector is connected with the connector socket, the first contact terminal to a first port of a codec circuit electrically connected with the connector socket through a first electrical path, to electrically connect the second contact terminal to a communication circuit through a second electrical path different from the first electrical path, and to cause the communication circuit to receive a radio signal through the second electrical path.
In a feature of the present disclosure, it is possible to enhance both audio performance and radio performance of an electronic device using, for example, an earphone as an antenna.

FIG. 4 is a diagram illustrating an example configuration of the electronic device according to various example embodiments of the present disclosure, and FIG. 5 is a diagram illustrating an example printed circuit board (PCB) according to various example embodiments of the present disclosure.
Referring to FIGS. 4 and 5, the electronic device 400 (e.g. electronic device 101 or electronic device 201) may include a codec circuit 410, a communication circuit 420, a connector socket 430, and a ground 440.
In an example embodiment, an external connector 300 having multiple contact terminals may be inserted into the connector socket 430 having multiple contact terminals in the electronic device 400. For example, the external connector 300 may be a 4 pole earphone. In this case, the external connector 300 may include a microphone terminal M, a ground terminal G, a right audio terminal R, and a left audio terminal L.
The connector socket 430 may be placed close to the opening formed on the housing of the electronic device 400. The external connector 300 having multiple contact terminals may be seated or inserted in the connector socket 430 through the opening. The connector socket 430 may be an earphone jack into which a 4 pole earphone can be inserted. For example, the connector socket 430 may include a first contact terminal 432 and a second contact terminal 433 which are configured to electrically contact one of multiple contact terminals (e.g. ground terminal G) of the external connector 300 when the external connector 300 is inserted into the connector socket 430. The connector socket 430 may further include a third contact terminal 435 and a fourth contact terminal 436 configured to contact the left audio terminal L of the external connector 300, a fifth contact terminal 434 configured to contact the right audio terminal R of the external connector 300, and a sixth contact terminal 431 configured to contact the microphone terminal M of the external connector 300.
The codec circuit 410 is disposed in the housing of the electronic device 400 and may be electrically connected to the connector socket 430. The codec circuit 410 may include a plurality of ports. For example, the codec circuit 410 may include a first port Ear_G (or ground terminal), second port Ear_G_det (or ground detection terminal), third port Ear_L_det, fourth port Ear_L, fifth port Ear_R, and sixth port Ear_M.
The codec circuit 410 may include a detection circuit to detect the connection of the external connector 300, and an audio circuit to transmit and receive an audio signal to and from the external connector 300. The detection circuit may include the second port Ear_G_det and the third port Ear_L_det. The second port Ear_G_det may be electrically connected to the ground terminal G of the external connector 300 through the second contact terminal 433 of the connector socket 430. The third port Ear_L_det may be electrically connected to the left audio terminal L of the external connector 300 through the third contact terminal 435 of the connector socket 430.
The second port Ear_G_det and the third port Ear_L_det may be connected to the voltage source VCC through a pull-up resistor R1. A first division resistor R2 and a second division resistor R2 may be placed between the second port Ear_G_det and the second contact terminal 433 and between the third port Ear_L_det and the third contact terminal 435, respectively.
In an example embodiment, the detection circuit of the codec circuit 410 may include the third port Ear_L_det only. The detection circuit may be configured as a separate entity or included in a different component (e.g. processor 120 or 210, or power management module 295).
The audio circuit of the codec circuit 410 may include the first port Ear_G, fourth port Ear_L, fifth port Ear_R, and sixth port Ear_M. The first port Ear_G is electrically connected with the first contact terminal 432 of the connector socket 430 and the ground 440, and may be electrically connected to the ground terminal G of the external connector 300 through the first contact terminal 432 of the connector socket 430. For example, the first contact terminal 432 and the first port Ear_G may be electrically connected using a first electrical path, and the ground 440 may be electrically connected with one side of the first electrical path.
A first inductance element (e.g. choke inductor L1) may be placed between the ground 440 and the first contact terminal 432 to prevent a radio signal received through the external connector 300 from being induced to the first port Ear_G.
The first port Ear_G and the first inductance element L1 (or, the first contact terminal 432 if the first inductance element L1 is not present) may be connected directly or indirectly through the ground 440.
The fourth port Ear_L may be electrically connected with the left audio terminal L of the external connector 300 through the fourth contact terminal 436 of the connector socket 430. The fifth port Ear_R may be electrically connected with the right audio terminal R of the external connector 300 through the fifth contact terminal 434 of the connector socket 430. The sixth port Ear_M may be electrically connected with the microphone terminal M of the external connector 300 through the sixth contact terminal 431 of the connector socket 430.
The communication circuit 420 may send and receive radio signals. For example, the communication circuit 420 may send and receive a radio signal through the external connector 300 connected to the connector socket 430. One constituent (e.g. ground line) of the external connector 300 may serve as an antenna for the communication circuit 420.
The communication circuit 420 may be electrically connected with the second contact terminal 433 of the connector socket 430 through a second electrical path different from the first electrical path. A DC-blocking element (e.g. capacitor C1) may be placed between the communication circuit 420 and the second contact terminal 433 to block supply of DC power (e.g. Vcc) to the communication circuit 420. A second inductance element (e.g. inductor L2) may be placed between the DC-blocking element C1 and the communication circuit 420 to reduce high-frequency noise. The DC-blocking element C1 and the second inductance element L2 may perform a filter function.
The communication circuit 420 may include a DMB module (not shown) to process a video broadcast signal and/or an FM module (not shown) to process a radio broadcast signal.
In various embodiments, referring to FIG. 5, there may be a first electrical path 510 between the first contact terminal 432 and the first port Ear_G, and a second electrical path 520 between the second contact terminal 433 and the communication circuit 420. There is no line common to the first electrical path 510 and the second electrical path 520. As the first electrical path 510 does not affect radio performance of the communication circuit 420, the line width may become larger. As the second electrical path 520 does not affect the ground of the codec circuit 410, the line width may become smaller for impedance matching. The second electrical path 520 may share a line with the second port Ear_G_det. However, as the second port Ear_G_det has only to sense a voltage change caused by the connection of the external connector 300, it may be not affected by the line width. In the present disclosure, the width of the line commonly used by the connector socket 430 and the second port Ear_G_det shown in FIG. 4 may be adjusted (e.g. decreased) for impedance matching. Hence, the electronic device 400 may achieve both audio performance and radio performance.
In an example embodiment, although not illustrated in FIG. 4, the electronic device 400 may further include various components, such as a digital sound player module like an MP3 module, short-range communication module, and a sensor module including an illuminance sensor, motion sensor, fingerprint recognition sensor, and infrared sensor.

Referring to FIG. 6, the electronic device 600 may include a codec circuit 610, a communication circuit 620, a connector socket 630, and a ground 640.
The configuration of the electronic device 600 may be similar to that of the electronic device 400 of FIG. 4 except that the external connector is a part of a balanced earphone and the connector socket 630 is an earphone jack for the balanced earphone.
The balanced earphone may have two right audio terminals Ear_R+ and Ear_R−, two left audio terminals Ear_L+ and Ear_L−, and a ground terminal G.

The connector socket 730 may be placed at a lower end portion of the electronic device 700. For example, the connector socket 730 may be placed next to the interface terminal 780. When a shared line is used while the connector socket 730 is separated far from the communication circuit 720 and the codec circuit 710 as shown in FIG. 7, it may be very difficult for the electronic device to achieve audio performance and radio performance at the same time. However, in the present disclosure, as separate lines are used, it is possible to achieve audio performance and radio performance at the same time although the connector socket 730 is placed at a lower end portion of the electronic device 700.
FIG. 8 is a flowchart illustrating an example method for the electronic device to receive a radio signal according to various example embodiments of the present disclosure.
Referring to FIG. 8, at step 810, the electronic device (e.g. electronic device 101 of FIG. 1, electronic device 201 of FIG. 2, electronic device 400 of FIG. 4, electronic device 600 of FIG. 6, or electronic device 700 of FIG. 7) detects whether an external connector is connected. For example, the codec circuit of the electronic device may detect the connection of an external connector by use of at least one of the second port Ear_G_det and the third port Ear_L_det illustrated in FIG. 4 or 6.
When an external connector is not connected, at step 870, the electronic device may perform a regular operation. For example, the electronic device may play music or access the Internet according to a user request, or may remain in the standby state.
When an external connector is connected, at step 820, contact terminals of the external connector are brought into contact with corresponding contact terminals of the connector socket. For example, a first contact terminal of the external connector and a first port of the codec circuit may be connected together through a first electrical path, and a second contact terminal of the external connector and the communication circuit may be connected together through a second electrical path different from the first electrical path.
At step 830, the electronic device determines whether the radio signal reception function is enabled (for, e.g., DMB video broadcast or FM radio broadcast). When the radio signal reception function is not enabled (off), the procedure proceeds to step 860. When the radio signal reception function is enabled (on), at step 840, the electronic device receives a radio signal by use of the second electrical path.
At step 850, the electronic device determines whether the radio signal reception function is disabled (off). When the radio signal reception function is not disabled (on), the procedure returns to step 840.
When the radio signal reception function is disabled (off), at step 860, the electronic device determines whether the external connector is disconnected. When the external connector is not disconnected, the procedure returns to step 830. When the external connector is disconnected, the electronic device ends radio signal reception through the external connector. Although only radio signal reception using the second electrical path is described in FIG. 8, the electronic device may use the second electrical path to transmit a radio signal or to transmit and receive a radio signal in another embodiment.
According to various example embodiments of the present disclosure, a method for transmitting and receiving radio signals in an electronic device may include: detecting whether an external connector having multiple contact terminals is connected with a connector socket having a first contact terminal and a second contact terminal that are configured to electrically contact one of the contact terminals of the external connector; and electrically connecting, when the external connector is connected with the connector socket, the first contact terminal to a first port of a codec circuit electrically connected with the connector socket through a first electrical path, electrically connecting the second contact terminal to a communication circuit through a second electrical path different from the first electrical path, and causing the communication circuit to receive a radio signal through the second electrical path.
In an example embodiment, detecting whether an external connector is connected with a connector socket may include causing a second port of the codec circuit electrically connected with one side of the second electrical path to detect whether one of the contact terminals of the external connector comes into contact with the second contact terminal of the connector socket.
In an example embodiment, detecting whether an external connector is connected with a connector socket may include causing a third port of the codec circuit electrically connected with a third contact terminal different from the first contact terminal or the second contact terminal to detect whether one of the contact terminals of the external connector comes into contact with the third contact terminal.
In an example embodiment, the method may further include causing the communication circuit to transmit a radio signal through the second electrical path.
